Question

I am trying to get information of remote file with curl. Problem is that other web-server is on port 81.

<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt ($ch, CURLOPT_PORT , 81);
curl_setopt($ch, CURLOPT_URL, 'http://98.246.25.185/server_status2.php');
$store = curl_exec ($ch);
echo substr($store, 1);
curl_close ($ch);
?>

And as you can see it doesnt work.

Answer 1

What happens if you specify the port number in the URI ?

What I mean is first remove the CURLOPT_PORT line, and, then, modify the CURLOPT_URL one to add the port number :

curl_setopt($ch, CURLOPT_URL, 'http://98.246.25.185:81/server_status2.php');

Edit after the comment : I just tryied this portion of code :

$ch = curl_init();
curl_setopt($ch, CURLOPT_VERBOSE, true);
//curl_setopt ($ch, CURLOPT_PORT , 81);
curl_setopt($ch, CURLOPT_URL, 'http://98.246.25.185:81/server_status2.php');
$store = curl_exec ($ch);
echo substr($store, 1);
curl_close ($ch);

And I get this output :

Online Peak: 59
Online: 17
Distributive server: Online
Agent server: Online

So, the code seems to be OK.

Are you sure there is not a firewall or anything or your network, that prevents you from doing HTTP requests on port 81 to that server ?

Does it work when you type that URI in your browser ?
